Honestly, Google or similar search tools are probably your best resource for acquisition of such images.
Linux systems with Open Office is an alternative to Apple or Microsoft.

What CERTAINLY must have been called out by now is the complete disconnect between "Electrical code issues" and the IEEE. Having been a member of the IEEE, the IAEI, the IBEW, and eng-tips for what I would consider various long times, I can say and will defend (if need be) that the the IEEE is...
The evident layout, workmanship, and maintenance conditions alone indicate that this sort of damage and collateral damage would happen, and will happen again. Shall I really discuss proximity, placement, fireproofing, securing of cables here? Need I point out collapsing vault walls, unbushed...
I've used plenty. You need to have a NEMA 4x rated device, for conventional limit switches I've mostly used Allen Bradley, Banner, and Square D on stuff I've built myself,but there's lots of different stuff out there. Availability is always an issue, and in the USA those 3 always have had good...
Well Kieth, I'll go along on most of that, but if you've got the CPU and the memory space, you know as well as any of us that verification of state/condition by a different means improves reliability. Certainly there are multiple affected IO, the status of which is effected by your pressures...
Sykki, I hope you've found a solution, and if so, I suspect we'll never be visited by you again. That only tells you a tiny bit about me. We still know nearly nothing about the mechanism(s) you sought help with.
After 35 years a handheld plastic dial Caliper or Vernier caliper, as are so...
I'm sorry if this produces a string of posts; apparently my Chrome browser and the website aren't playing nicely together lately.
Adding additional gas beyond your added capacity will of course produce a higher system pressure and also change the compression curve on your inert gas. This will...
You probably know everything here, but the link may put much of it in a structure or light that you may find helpful:

There's a paper speaking directly to this problem published by Electrofed in 2013. Google brings it up instantly under "Electronic Ballast Inrush current".
I don't typically work at the circuit board/design level, but I suspect that it wouldn't be particularly difficult or expensive to...
Agree with jraef. It essentially has its own protection.
If this actuator is particularly crucial it should be protected by sensing it's position and tripping an alarm if it is not in the proper position(s) within an appropriate time of its actuation/deactivation.

So, you got your answer here already. I'll only go further to tell you, apparently somebody that has some responsibility for this project or facility, that you're seeing ranges of values instead of fixed figures, and there are firm reasons for that. If this unit is important and may have high...
More agreement with jraef. The idea of changing to a smaller motor is unwise and ill-considered. If someone with such little technical knowledge insists on invading and changing a functioning mechanism, properly designed and implemented in its current state, additional changes will also be...
Golly Kieth, you're usually the one giving us the answers! Now c'mon, I'd bet one of the first PLC jobs you did that's worth remembering was,,,, somebody that wanted ("needed") more I/O! (On a Modicon?)
We knew you'd get it, and were just, uh, well,,, let's say "indecisive" at the moment...
You have a final personal security mechanism available to you; the log book. You should keep a log of what you sign, and with today's "cloud" it's quite easy to have at least a cloud based backup copy. It is valuable, and should be kept secure by whatever means you prefer.

Tips?
- a Yankee screwdriver works very well; a little speed with good feel
- a long-nosed pliers, and a bent-nose-long-nosed pliers.
- a dental inspection mirror
- a small bright flashlight; 1xAA or 1xAAA
- remember, it's conductive, firm connections you're going for NOT tight screws (yeah, we...
Yes I have. Many/most have been due to "wiring problems" particularly terminations of conductors at terminal strips (particularly where "combs" are used across multiple terminals) or multiconductor cable connectors in the main control panels/MCCs. Don't quickly rule that out.

Yes, there certainly is a written guideline, and it will use current to determine capacity of wiring and switches, but there may be a maximum quantity of connected devices specification as well. That said, you may well find that many technicians speak or think in kilowatts, which are...
The response by rotw is very accurate. I find your actions to be rather abrupt. It would appear that you are now in a less influential position, and probably unprepared for the most likely outcomes. "This company has been around for many years..." so, obviously they have many contacts and...
Good eye for noticing things that aren't quite right. As some of these replies have shown, there may be some plausible explanations for aspects of what you describe. Still, if something looks rotten, smells rotten, feels rotten, and sounds rotten,,, it's probably rotten. You don't need to...
